[R-SIG-Mac] GTK+ libraries can't be found

Dear Simon,

First of all many thanks for the guidance and more generally for the  
great stuff you do for the R Mac community.

On the environment, I have added the line you suggested to  
both .bash_profile and .profile, but R does not seem to be looking  
there (bash certainly does).  Where does the GUI R get the environment  
definitions from?  And more generally where can I look more closely to  
the startup process for R GUI as I have not yet managed to get it to  
read the ~/.Rprofile file (and the definitions therein) properly [I  
have tinkered with the preferences with no success]

On the availability of the binary for RGtk2 on CRAN and its mirrors, I  
am afraid that it does not appear in the ones I have tried (Munchen  
and the first US).  Should I be using another mirror that is more  

If I may, could I suggest an addition and one modification to the  
keyboard shortcuts for R GUI?  The addition would be to add "run  
function definition", possibly as shift-cmd-return, to take multiline  
commands in R, something usually done for more involved call (such as  
aggregate, merge, etc.).  Also, could the default cmd-return (or a  
variation of it) then move the cursor to the next command/uncommented  
line?  This would reduce the required keystrokes of my tipical  
sessions by half.  Many thanks in advance for considering this.

kind regards,
